It is important to analyze edible oils and fats such as palm oil to monitor the levels of potential carcinogens such as 3-MCPD, 2-MCPD and glycidyl ester. As increasing numbers of analyses are required for monitoring food safety the use of an automated liquid handling robot system becomes advantageous for the preparation of samples in the most efficient and reliable manner possible.
The automated high throughput sample preparation system LISSY-MCPD performs four different well-established methods to analyze 3-MCPD (free and ester form), 2-MCPD and glycidyl ester in oil and fat samples. Dependent on the sample matrix or the analytical needs, the methods can be changed from Cd 29a-13  to Cd 29b-13 , to Cd 29c-13 , to EN-779  or any combinations of the AOCS methods with the EN-779. Also other liquid / liquid extraction methods (LL) can be established on the system.
In upgraded versions, combinations of solid phase extraction (SPE) and liquid / liquid extraction methods for MOSH, PAH, PCB, AOX, EOX are possible.
The throughput of the single methods is dependent on the workflow itself:
The results from the automated workup have been tested and are comparable with manual methods, with the automated workflow providing better variability.
The combination of a reliable and high-speed robotic sample process and a selection from Zinsser's many unique tools will offer you the opportunity to automate your sample preparation processes for the best benefit of speed, labor-savings, efficiency and accuracy.
